Which statement is false about cancer cells?

The statement that cancer cells are anchorage-dependent is false. In normal cell biology, anchorage dependence is a vital property of many types of cells, meaning they require attachment to a solid surface or extracellular matrix to grow and divide. This mechanism ensures that cells only proliferate in their proper locations within tissues.

In contrast, cancer cells often lose this property. They can grow and divide without being attached to a substrate, allowing them to proliferate inappropriately and invade surrounding tissues. This lack of anchorage dependence contributes to the aggressive nature of cancer, as it facilitates uncontrolled growth and the potential for metastasis—spreading to other parts of the body.

The other statements accurately reflect characteristics of cancer cells. They have uncontrolled division, enabling them to proliferate and form tumors. They also exhibit the ability to survive without the normal requirements for attachment, which is a feature that distinguishes them from healthy cells. Additionally, cancer cells can invade other tissues, which is a hallmark of malignancy and illustrates their capacity to disrupt normal cellular organization.
